In the Dujiangyan Project, Feisha Dyke is one of the three most important parts. Rather ordinary as it looks, it plays a significant role that prevents Chengdu Plain from suffering floods. The Feisha Dyke joins the inner and outer canals. The dyke functions to controll the flow of water and discharge excess into the inner canal from the main stream. During the dry season the dyke doesn't work much, but when floods occur, the river rushes forward along the outer canal. As it approaches the dyke, the river begins to turn round fast and soon many whirlpools are formed. The volatile whirlpools sweep away sand and pebbles and throw them into the outer canal. For many years huge bamboo cages were used as the fence. They were filled with stones and pebbles. However,at present, reinforced concrete weir has replaced the ancient fence. Nowadays, the bamboo cages are still widely used in the farmlands. Farmers use them to discharge the water and irrigate the farmland.
